Why would a drug that damages capsids help treat a viral infection

Answers

The capsid is the protein shell that surrounds the core of a virus where its nucleic acid is located. The capsid is made up small sub units called capsomeres.A virus consists of a nucleic acid which may either be RNA or DNA and is found in varying quantities in the virus. It is this nucleic acid that is vital to the virus' survival that is housed in the capsid.A drug that targets the capsid and damages it will cause the nucleic acid to leak out of the virus and into the surrounding while other fluids foreign to the virus will get in rendering the virus totally impaired, and due to this the virus cannot survive but will speedily die.

What cell activity is depicted in the figure?A) ATP production
B) DNA replication
C) protein synthesis
D) mRNA transcription

Answers

Answer: DNA replication

DNA replication occurs in the nucleus (eukaryote cells). DNA replication occurs in the interphase when the cell is growing, its carrying processes and its replication it’s DNA  

Once the cell is replication it does not divide so both theses process are not carried out together .Helicase is the unzipping enzyme. DNA polymerase, replicates the DNA molecules to actually build a new strand of DNA. Primase acts as an initializer  


DNA replication

Because, and to be honest there isn't much explanation to give since it's pretty much something we have to remember by heart more than anything, some of the enzymes a specific to this kind of process and isn't there in, for example, mRNA transcription.

Which mechanism do sponges possess that makes a predator think twice before attacking it?

Answers

Answer:

Sponges come under phylum Porifera. They exhibit cellular levels of body organization and are inactive in nature. The sponges are known to generate and discharge some kind of toxins. The discharging of the toxins may perform various activities like shielding themselves against the parasites and predators. However, these toxins are also considered to harm other sponges.  

This mechanism of sponges makes a predator think two times before attacking it. The sponge will generate toxins, which could disorder the metabolism of any species that try to eat them. However, the majority of the predators possess the tendency to detect the toxin via their sense of smell, and thus, helps them in avoiding the sponges.  

Sponges possess the defense mechanism of releasing toxins that make a predator

A scientist is using a ­computer model to predict changes to a population of ­rabbits in a meadow. Identify the information about the rabbit population that should be included in the computer model.

Answers

Answer:

In the mentioned case, the intrinsic and environmental factors influencing the size of the population should also be included in the computer model. The population size is primarily predicted by environmental and intrinsic factors.  

The size of the population of any species is monitored by the factors like birth rate, death rate, limiting factors, and their accessibility, carrying capacity of the system, rate of migration, and others. All these elements should be taken into consideration in order to determine the changes observed in the population of rabbits in a meadow.
